ahoffmannCommented:
hmm, don't know what nl2br() does, assuming that it converts 0x0a to <br > then according your question:
> ... how to not add <br / > 
simply do not call it

may be I don't understand what you want to archive, but your description is very vage ...

about code it work but.

in tag code

[ code ]
if()
{

}
[ /code ]

PHP Code Line :

$bbcode = nl2br($str);

Output :

[ code ]
if()<br />
{<br />
<br />
}<br />
[ /code ]

it add <br /> in code. but i not need <br /> add in tag code

then not use nl2br() function, in tag \n not work display on html code.

ahoffmannCommented:
you need to parse your code and exclude those parts which you define as code from being passed to nl2br()

You need a good parser for that as it cannot simply be done with regex, see this example

[ code ]
if(x=="[ /code ]"){
  bang="\
[ code ]  \
";
/*
[ /code ]
*/
hidden=true;
}
[ /code ]

   int li_8 = Bars - ind_counted_0;
   if (li_8 > 1) li_8 = Bars - 3;
   double ld_12 = p / 100.0;
   for (int li_4 = li_8; li_4 >= 0; li_4--) {
      if (Close[li_4] < gd_132) {
         gd_132 = Close[li_4];
         gd_148 = gd_132 * (2.0 * ld_12 + 1.0);
         gd_140 = gd_132 * (ld_12 + 1.0);
      }
      if (Close[li_4] > gd_148) {
         gd_148 = Close[li_4];
         gd_132 = gd_148 * (1 - 2.0 * ld_12);
         gd_140 = gd_148 * (1 - ld_12);
      }
      g_ibuf_120[li_4] = gd_148;
      g_ibuf_124[li_4] = gd_140;
